If fluid builds up around the lungs, the patient may find it hard to breathe. She may also suffer from itching skin and dry mouth, explains Kidney Cares Community.

There are basically three causes of uremia, notes Kidney Cares Community. With prerenal causes, the flow of blood to the kidneys is decreased through trauma, heavy blood loss and infections.
